If a person forgot to make Sajdah Sahw and while engaging in Tasbeeh, etc., remembers, what should he do?

Answer

As long as he did not turn away from the Qiblah nor did anything which breaks Salaat, e.g. speak, walk, etc., then he should immediately make the Sujood Sahw, then recite Tashahhud, Durood, Dua and make Salaam even if he remembers after having recited Tasbeeh, etc.
